Control of mastitis
First Claim
1. A method for killing mastitis-causing gram negative organisms including Pseudomonas aeruginosa, Escherichia coli, or Klebsiella pneumoniae or gram positive organisms including Staphylococcus auereus on an animal'"'"'s teats comprising the step of treating the teats of the animal with an thickened aqueous medium formulated to ensure a contact time between the teats and the medium of 15 seconds to 15 minutes, the medium comprising:
- (a) anionic surfactant of the formula
space="preserve" listing-type="equation">RAO.sub.x.sup.-.sub.M.sup.+ wherein R is essentially organic, A is sulfur or phosphorus, x is 3 or 4, and M is topically acceptable cation; and
(b) a pH modifying or maintaining substance in an amount sufficient to adjust a pH of the composition to a value in the range of 2.0 to 5.0.

Abstract
A mastitis controlling method and composition based upon anionic surfactants of the formula
R--AO.sub.x.sup.- M.sup.+
which generally includes organic sulfonates, sulfonic acids, phosphonates and phosphates, the composition being maintained in a pH range of 2.0 to 5.0 (preferably 2.1 to 4.0, and most preferably 2.5 to 3.5). Rapid kill of mastitis-causing gram positive and gram negative microorganisms is achieved in the practice of the instant method.
